IMPROVEMENT IN SHAFT-COUPLINGS.

The v.'leheduie referred to ln these Letters Patent end maklng part o f the same.

To all whom, it may concern: I

Be it known that I, PETER W. REINSHAGEN, of Cincinnati, Hamilton county, State of Ohio, have invented a certain new and useful Improvement in Shaft-Couplings; and I do declare the following torbe a full, clear, and exact description thereof, reference being had to the accompanying drawing making part of this specification.

Nature (tml Objects of I )went/ion.

General Description. A is a sleeve, bored to it the shaft to be coupled, and turned doubly tapering upon the outside, as

shown.

It is split or cut through on both sides at a and a?, by means of a milling tool or other snitable'instrument, the cuts commencing, as shown, from opposite ends, as well as opposite sides, and terminating be- 'fore the sleeve is .ont in two.

This device, it will be seen, retains the sleeve in one piece, lwhich is a very important feature, makes a double cut to obtain a great range of elasticity,l and still secures an equalpressure upon the shaft throughout the entire length of the sleeve when compressed. The rings B B', being bored tapering to tthe sleeve, serve to compressthe sleeve when driven on, although other devices may'be used to accomplish thesane result. l

Claim.

In connection with suitable compressing devices B B', or equivalent, the spring sleeve A a af, when the same is split from opposite ends and opposite sides, in the manner and for the purpose set forth.

In testimony of which invention I hereunto set my Felini: MiLrJWARo, "J. L'. WABTMANN.
